Every public company enters a black-out/restricted period 2 weeks before the close of a quarter (due to having access to potentially materials non-public information). That earnings-related period ends like 48 hrs. after the company files its financial statements with the SEC.
But don't take my word for it, look it up at the SEC or NASDAQ (and certainly, ignore the mindless drivel posted by Captnstoopid).
There's no blackout period, VP. The share buyback status was discussed on the annual conference call and there was no mention of any sort of blackout period. That one gets his knowledge from a crackerjack box. 🤣
